This is a simulation showing how Australia could meet its electricity demands using a large amount of additional renewable capacity.

Unfortunately the Australian electricity generation mix as of 2020 is made up of 54% coal and 20% and just 24% renewables [1]. Renewable capacity is increasing but at the current pace 90+% renewable generation is not likely to be achieved within the next 20 years.

You can check the live generation mix on electricitymap [2].

They transitioned 3.5% of grid supply last year, and that's actually an underestimate of the transition since it doesn't factor in behind-the-meter use of solar. Solar adoption has also accelerated over the last couple of years, up from 23% growth over 2019 to 42% growth last year. I wouldn't be surprised to see an almost full transition in the next 10 years.

According to:

https://en.wikipedia.org/wiki/Solar_power_in_Australia

Yearly PV capacity increase is between 3 and 4 GW, so tripling PV as the simulation assumes starting from 27 GW means between 11 and 15 years to reach at the current rate.

I did not look for wind data (yet).

If you do the increase as a percentage, say 20% yearly growth in output, which probably better fits the history and other countries, then it's about half that time to triple.
